Bug Description
Plasma 5.12.3 was working fine on Kubuntu 17.10 plus backports ppa
On upgrading to Kubuntu 18.04 beta, plasmashell crashes every login leaving an empty black screen. Applications can still be launched via Alt-Space.
The only clues I can see are:
1. .xsession-errors contains:
KActivities: Database can not be opened in WAL mode. Check the SQLite version (required >3.7.0). And whether your filesystem supports shared memory
followed by multiple reports of:
KActivities: FATAL ERROR: Failed to contact the activity manager daemon
2. /home is an NFS share
Does NFS support shared memory?
If I unmount /home and use a local /home, copy all config folders from the NFS to the local home, then all seems fine.
sqlite -version says 2.8.17
